In the invention, digital signatures with timeliness are distributed to a service data sender, a service data transfer node and a service data receiver through a signing server, service data is digitally signed by the data sender, and the service data receiver authenticates whether the service data sender is legal and whether the data is falsified according to the digital signature. In the invention, the safety of transfer data is enhanced due to the data signature technology, and the safety data transferring method and system ensure that the transfer node only transfers legal data only and the data receiver only receives the legal data.
Description
Technical field
The present invention relates to the mobile immediate communication field, relate in particular to a kind of method and system by third party's node security interim data.
Background technology
Immediate communication tool is very universal now, and except satisfying the interchange of user's common language, picture, the interchange of voice, image is also universal day by day.Visual telephone is the developing direction of immediate communication tool.But complicated network environment is any network communication software all must be faced and overcome.Because the Internet agreement (use increasingly extensive for Intemet Protocol, the IP) scarcity of address by the NAT technology.A lot of private users all are positioned at network address translation, and (Network Address Translation, back NAT) is connected on the Internet by router, can not direct-connected communication between this class user.This moment must by the UDP simple traversal of NAT (Simple Traversal of User Datagram Protocol through Network AddressTranslators, STUN) or TURN (Traversal Using Relay NAT) technology set up path.Using third party's node in interim data, the both sides of communication need do affirmation to the data source, prevent to receive the packet from forging client; Simultaneously, transit node just needs also to confirm whether two nodes in the transfer service are legal node, in order to avoid to the waste of transit node resource.
The prior art transit node confirms whether legal method has following two kinds to data source:
Method one, use IP and port are judged, come according to the IP address and the port numbers (Port) of packet whether the judgment data bag is the packet of professional both sides' node transmission.In case find that the address or the port of packet are not right, think that just this packet is an illegal packet, turn out in no longer.If this address and port are on all four, can think that then this packet is legal data.The shortcoming of this method is, if the address of data receiver or port often change, and the validity that transit node can not recognition node, thus cause refusing data from validated user.
Method two, use a certain value except IP address and Port is as the standard that judges whether legal data.For example carry data source in the packet ID number, when transit node is received packet,, think that just these data are invalid datas if judge that the ID in the matched data bag and the node of application service are not same ID, refusal is transmitted.If consistent, then think a legal packet, and do to transmit operation.The shortcoming of this method is that if this fixed value is obtained by the four directions, it is legal that the data that the four directions sends are just thought by transit node, and transmit, and is easy to generate potential safety hazard.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of secure data transfer method and system, is used to solve the authentication of the Data Source by third party's node interim data time the and the technical problem of data security.
For achieving the above object, based on an aspect of of the present present invention, shifting method in a kind of secure data is proposed, comprising:
The business datum sending node carries out after the digital signature business datum and digital signature field packing being sent to transit node to business datum;

Embodiment
Basic thought of the present invention is: divide hair band ageing digital signature by signature server to business datum transmit leg, business datum transit node, business datum recipient, the transmit leg of data carries out digital signature to packet, and whether a square tube of reception data is crossed digital signature and come the transmit leg of authentication data packet legal.The transit node of business datum is by the transmit leg of digital signature identification business datum, if authentication is not by then refusing the forwarding operation data; The recipient of business datum if authentication is not passed through, then rejects the business datum of transit node transfer by the transit node of digital signature identification business datum.The present invention has strengthened the fail safe of interim data by the data signature technology, guarantees the legal data of a transit node transfer, and the data receiver receives only legal data.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the composition structural representation of secure data transfer of the present invention system, this system comprises service node, transit node and signature server, as shown in Figure 1, transmit business datum by transit node between service node A and the service node B, signature server is used to service node and transit node that the digital signature service is provided, and the plaintext at random or the key that are used for digital signature in another specific embodiment of the present invention have ageing.
Fig. 2 is that transit node of the present invention transmits the program execution flow figure of business datum, and below to send business datum with service node A to service node B based on the system configuration of Fig. 1 be the transfer process that example is described business datum in detail, and concrete steps are as follows:
Step 201: signature server is that service node and transit node issue plaintext or the key at random that is used for business datum is carried out digital signature; The business datum sending node uses the plaintext at random or the key that obtain to carry out digital signature to sent business datum, generates digital signature field, and business datum and digital signature field packing are sent to transit node;
Signature server among the present invention is responsible for producing and is safeguarded that the transfer three parts carries out digital signature employed plaintext or key at random to business datum.After the professional beginning, transit node, business datum sending node and business datum receiving node obtain described plaintext or key at random according to agreement or the algorithm with the signature server agreement from signature server, wherein the business datum sending node obtains one group of identical plaintext or key at random with transit node, also obtain other one group of identical plaintext or key at random between transit node and the business datum receiving node from signature server, suppose that business datum sending node and transit node obtain one group at random expressly or key be S1, transit node and business datum receiving node obtain one group at random expressly or key be S2, then can have two groups of plaintext or keys at random simultaneously at transit node, S1 is used for the packet of business datum sending node is authenticated, S2 is used for the business datum of transmitting is carried out digital signature once more, and the present invention is not to key S1, form that S2 is concrete and the generating algorithm that is adopted limit.
Step 202: after transit node receives business data packet, take out the digital signature field in the packet;
Step 203: whether the determination number word signature is expired, if expired then execution in step 204, otherwise execution in step 205;
Preferably, the plaintext at random or the key that are used for digital signature that produce on the signature server have ageing, purpose is the raising Information Security, increases and crack or difficulty of attacking that the present invention does not limit and makes described plaintext at random or key have ageing algorithm that adopts and agreement.
Step 204: upgrade local plaintext or the key at random that is used for digital signature, execution in step 205 then;
When service node or transit node find to be used for digital signature at random expressly or key when expired, can by with renewal protocol update this locality of signature server agreement at random expressly or key, the recipient of business datum also can find when inconsistent in the authentication digital signature, by trend signature server acquisition request new at random expressly or key.A kind of simple method can be: service node or transit node at random expressly or key when expired initiatively to signature server please look for novelty at random expressly or key, between the sending node that guarantees business datum by signature server and the receiving node of business datum at random expressly or key synchronous.
If adopt non-ageing at random expressly or key, but then the digits deleted signature is expired and at random expressly or the key updating process.
Step 205: transit node extracts the digital signature field that transmitting terminal generates from business data packet, and uses local plaintext at random or key to generate new digital signature field according to the algorithm identical with transmitting terminal;
Step 206: judge whether the digital signature field of carrying in the local digital signature field that produces and the business data packet that receives is consistent, as if unanimity execution in step 207 then; Otherwise execution in step 208;
Step 207: the transit node transfer should be arrived the receiving node of business datum through the packet of authentication;
Transit node use other one group at random expressly or key business datum is carried out digital signature, generates new digital signature field, business datum and this digital signature field are packed sends to the business datum receiving node.The process that the data that the business datum receiving node forwards transit node authenticate is similar to the processing procedure of transit node, repeats no more herein.
Step 208: transit node abandons this not packet by authenticating.
Below be that example illustrates the transfer process of business datum being carried out digital signature and business datum with the rivest, shamir, adelman:
Signature server is that business datum sending node and transit node generate a pair of PKI and private key (P1, S1), for transit node and business datum receiving node generate another to PKI and private key (P2, S2), the business datum sending node at first uses the HASH algorithm of agreement that the data that send are produced 128 digital digests that are, use private key S1 that digital digest is carried out digital signature then, summary packing with business datum and after encrypting sends to transit node, the transit node summary of P1 after to the encryption that receives that use public-key is decrypted, transit node uses the HASH algorithm identical with transmit leg to generate the summary of business datum simultaneously, summary after will deciphering is then compared with local newly-generated summary, if but consistent then verification msg bag is sent by transmit leg, and information does not have destroyed or distorted in transmission course, otherwise illustrate that packet is destroyed or by being distorted in transmission course, or packet not to be sent by correct transmit leg.If transit node is verified not by then abandoning this packet business data packet, generate 128 digital digests that are if treat the business datum of forwarding by the HASH algorithm of then reusing agreement, use private key S2 that digital digest is carried out digital signature then, with packet and the summary after encrypting send to the business datum receiving node after repacking, the business datum receiving node P2 that uses public-key is decrypted the summary of the encryption that receives, the business datum receiving node uses identical HASH algorithm to generate the summary of business datum simultaneously, summary after will deciphering is then compared with local newly-generated summary, it is if consistent then but the verification msg bag is to be sended over by correct transit node, and information does not have destroyed or distorted in transmission course, otherwise illustrate that packet is destroyed or by being distorted in transmission course, or packet not to be sent by correct transit node.
The present invention does not limit the method for business datum being carried out digital signature, for example in to the not high scene of security requirement, digital signature is carried out in unique identification or IP address that can the business datum transmit leg, the sign or the IP address that only need extract transmit leg the recipient of business datum from packet header can generate new local digital signature, have improved treatment effeciency.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
